Thermal Design Engineer, Leo; Satellites

Thermal Design Engineer

Amazon Leo is Amazon's low Earth orbit satellite network. Our mission is to deliver fast, reliable internet connectivity to customers beyond the reach of existing networks. From individual households to schools, hospitals, businesses, and government agencies, Amazon Leo will serve people and organizations operating in locations without reliable connectivity.

We're looking for a Thermal Design Engineer who combines superb technical, research and analytical capabilities with a demonstrated ability to get the right work done quickly and effectively. This person must have experience working in spacecraft design, producing top notch thermal analysis and providing essential thermal related input and recommendations to vehicle architects and subsystem leads.

Key job responsibilities:

• Support extensive architectural trades by performing preliminary thermal analysis of spacecraft and subsystems for orbital operational conditions and vehicle control options.
• Perform conceptual through detailed thermal analysis of Bus and Payload subsystems, components, and mechanisms.
• Support thermal design activities for additional future programs as the Amazon Leo constellation evolves.
• Develop automated scripts enabling rapid analysis updates to accommodate design trades (power states, duty cycles, structural mapping).
• Design, analyze, and select heat pipes for Bus and Payload components.
• Define and execute thermal cycling and TVAC tests for development and qualification testing at the subsystem and vehicle level. Correlate test results with mission operations models.
• Define and select test equipment as needed (e.g., sensors, data logging equipment).
• Perform thermal model correlation using test results.
• Conduct testing of prototypes and engineering models for fast design feedback loops.
• Plan and execute characterization, qualification, and acceptance tests.
• Document trades and design evolution, and prepare materials for design review gates.
• Support thermal design for terrestrial equipment and systems using CFD analysis.

About the team Amazon Leo's Thermal Team is responsible for the thermal design solutions for all components in Amazon Leo's satellites and customer terminals. We work together with many engineering disciplines (e.g., mechanical, power, electrical, network, manufacturing) to find designs that maximize performance while minimizing mass, cost, and manufacturing complexity, and enabling all components to operate reliably over the satellite's target lifetime.

The team follows all hardware components from conceptual design through detailed analysis, development testing, launch, and flight.
